-Leon the Professional

This quote from my favorite movies rings true for killing people AND photographing people. I like making parallels between assassination and photography. You can change it to:

The telephoto lens is the first weapon you learn how to use, because it lets you keep your distance from the client. The closer you get to being a pro, the closer you can get to the client. The super wide-angle lens, for example, is the last thing you learn. 

Now if you’ll excuse me, I need to find a trusty sidearm to use with my rifle.
